When a man has dealt with so much stress, from relationships, careers, friends etc. That he turns into an individual of bottled up psychotic rage, clearly unstable. So unstable in fact, that not even a women PMSing will dare to cross his temper. He will be calm at first, but certain things to nothing at all will set him off on a lethal rampage of death and destruction. The closest thing to a fucking werewolf a human can get.

My friend has been afflicted with "Glass Shell syndrome"... And now they are tracking him in the woods by huge footprints and claw marks.. and the blood trails...
